ocvMxArrayFromImage_{DataType}

Convert row major cv::Mat to column major mxArray for image

C++ Syntax

#include "opencvmex.hpp"
mxArray *ocvMxArrayFromImage_double(const cv::Mat &in);
mxArray *ocvMxArrayFromImage_single(const cv::Mat &in);
mxArray *ocvMxArrayFromImage_uint8(const cv::Mat &in);
mxArray *ocvMxArrayFromImage_uint16(const cv::Mat &in);
mxArray *ocvMxArrayFromImage_uint32(const cv::Mat &in);
mxArray *ocvMxArrayFromImage_int8(const cv::Mat &in);
mxArray *ocvMxArrayFromImage_int16(const cv::Mat &in);
mxArray *ocvMxArrayFromImage_int32(const cv::Mat &in);
mxArray *ocvMxArrayFromImage_bool(const cv::Mat &in);

Arguments

in

Reference to OpenCV cv::Mat with row major data.

Returns

Pointer to a MATLAB^® struct, mxArray, with column major data. Supported data types:

real_T (double)	uint8_T (uint8)	uint32_T (uint32)	int16_T (int16)
real32_T (single)	uint16_T (uint16)	int8_T (int8)	int32_T (int32)

Description

The ocvMxArrayFromImage_{DataType} function creates an mxArray from a cv::Mat object. The mxArray contains column major data and the cv::Mat contains row major data.

This function is not a generic matrix conversion routine. For 3-D images, it takes into account that the OpenCV format uses BGR ordering and manipulates the data to comply with that formatting.
